Managing System Files
Setting the System Clock
Setting the System Clock
The switch clock displays time by using a 24-hour clock format. It can also be set for use in any time
zone. Daylight Savings Time (DST) is supported for a number of standard time zones. DST parameters
can be programmed to support non-standard time zones and time off-set applications.
All switch files and directories listed in the flash directory bear a time stamp. This feature is useful for file
management purposes.
Setting Date and Time
Date
You can set the local date, time zone, and time for your switch or you can also set the switch to run on
Universal Time Coordinate (UTC or GMT).
To display the current system date for your switch, use the system date command. If you do not specify a
new date in the command line, the switch will display the current system date.
To modify the switch’s current system date, enter the new date with the command syntax. The following
command will set the switch’s system date to June 23, 2002.
-> system date 06/23/2002
When you specify the date you must use the mm/dd/yyyy syntax where mm is the month, dd is the day and
yyyy is the year.
Time Zone
Time
To determine the current time zone or to specify a new time zone for your switch, use the
system timezone command. This specifies the time zone for the switch and sets the system clock to run
on UTC time (or Greenwich Mean Time). The following is displayed for the Pacific standard time zone:
-> system timezone
PST: (Coordinated Universal Time) UTC-8 hours
To set a new time zone for the system clock, use the system timezone command along with the appropriate
time zone abbreviation. Refer to the table in “Daylight Savings Time Configuration” on page 2-18 for
time zone abbreviations. The following command sets the system clock to run on Pacific Standard Time:
-> system timezone pst
To display the current local time for your switch, use the system time command. If you do not specify a
new time in the command line, the current system time is displayed as shown:
-> system time
17:08:51
To modify the switch’s current system time, enter the system time command. When you specify the time
you must use the hh:mm:ss syntax where hh is the hour based on a 24 hour clock. The mm syntax
represents minutes and ss represents seconds. You must use two digits to specify the minutes and two
digits to specify the seconds. The following command will set the switch’s system time to 10:45:00 a.m:
-> system time 10:45:00
